An inert purge involves pressurizing a vessel with inert gas and then relieving pressure.

An inert purge involves pressurizing a vessel with inert gas and then relieving pressure.

• A. True
• B. False
• C. Not sure
• D. Not applicable

Answer: (A)

Inert purge means flushing a vessel with an inert gas to push out air and hazardous vapors. The process typically starts by introducing inert gas to raise the internal pressure, which helps displace the existing atmosphere and vapors. After the purge has done its job, the system is vented to relieve the pressure back toward ambient. That sequence—pressurizing with inert gas and then relieving pressure—is the essence of an inert purge, so the statement is correct. Choosing something else would ignore the practical steps used in purging, which involve both raising and then releasing pressure to safely complete the purge.
